Printer calibration
Calibration settings are configured with Printer Management Language (PML)/Printer Job Language
(PJL) commands, except for new cartridge installation. Calibration can also be configured using the
HP Toolbox. Calibration occurs during the following conditions and intervals:
● Power-on calibration
Calibration during power-on can be configured for the following intervals:
●
Always calibrate at power-on
●
Never calibrate at power-on
● Calibrate after 1-6 minutes (default is 15 minutes) of idle time after the first job since the
printer was turned on or 12, 24, 48, 96, or 168 hours (default is 48 hours) of idle time.
● Page count calibration
Calibration occurs at the end of the first job that passes 150 color pages since the previous
calibration occurred. Page count calibration settings can be configured for the following intervals:
●
Do not do page count calibrations
●
Calibrate after 150 pages have been printed since the last calibration. This is the default
setting.
●
Elapsed time calibration
Elapsed time calibration will occur when the first job is sent after the elapsed time is exceeded.
Use PML/PJL commands to configure the following intervals:
●
Do not perform elapsed time calibration
● After 12, 24, 48, 96, or 168 hours (default is 48 hours) or more have elapsed since the last
calibration (or power-on), and after 1-6 minutes (default is 15 minutes) of idle time from the
first job after 12, 24, 48, 96, or 168 hours (default is 48 hours) have elapsed.
●
On-demand calibration
Calibrate the printer using the printer control panel. For more information about printer
calibration, see
Printer calibration on page 146.
●
New consumable calibration
When a new print cartridge is installed, the printer will calibrate.
NOTE When a new black print cartridge is replaced, a cleaning page will print before
the printer calibrates.
If printing stops when the cartridge is out, requiring the user to either install a new cartridge or
select to print with toner out override, a calibration will not occur until the depleted cartridge is
replaced, printing resumes, and all jobs currently in the queue are finished or cancelled. This
could result in an interval of several pages where a new cartridge is using the old cartridge’s
calibration data.
